Quick recap
Closing the arc that runs from 61 Hours, Reacher reaches the headquarters of the 110th MP in northeastern Virginia. He expected to meet the new commander, Major Susan Turner, but she has been arrested. Soon Reacher is taken into custody too, awaiting trial for two crimes he allegedly committed while in the Army. From there the book is a race to clear his name and hers, and to find out who set it all up.
